请教关于用squid在redhat linux下面做二级代理

各位大哥，请教关于用squid在redhat linux下面做二级代理的问题

我已经设置如下：(均采用默认端口）
cache_peer 代理服务器：代理服务器端口 parent 3128 3130 login=user:password

cache_peer_domain 代理服务器 .com
cache_peer_domain 代理服务器 .net
cache_peer_domain 代理服务器 .edu
cache_peer_domain 代理服务器 .cn

客户端设置好了以后，连不上，ie显示错误如下：

ERROR
The requested URL could not be retrieved

--------------------------------------------------------------------------------

While trying to retrieve the URL: http://www.163.com/

The following error was encountered:

Access Denied.
Access control configuration prevents your request from being allowed at this time. Please contact your service provider if you feel this is incorrect.

Your cache administrator is root.
